Laum Khoom: Cov yam ntxwv tseem ceeb ntawm cov khoom lag luam zoo

Laum cov khoom lag luam yog cov cuab yeej tseem ceeb rau ntau yam kev lag luam, los ntawm kev tsim kho rau kev ua ntoo. Lawv tuaj nyob rau ntau qhov ntau thiab tsawg thiab cov ntaub ntawv, tab sis muaj ob peb qhov tseem ceeb uas txhais tau tias yog laum zoo.

Firstly, cov khoom siv ntawm cov laum me ntsis yog qhov tseem ceeb. High-ceev steel (hss) yog cov khoom siv feem ntau, raws li nws ruaj khov thiab tuaj yeem siv rau ntau yam kev siv drilling. Cobalt Steel thiab carbide-tipped tho cov khoom me tseem yog nrov rau lawv cov kev ruaj khov thiab kub ua kom tsis taus.

Thib ob, kev tsim cov laum yog qhov tseem ceeb. Cov duab thiab lub kaum sab xis ntawm lub hau tuaj yeem cuam tshuam rau kev ua kom nruj thiab raug. Ib qho ntse, taw qhia yog qhov zoo tagnrho rau drilling los ntawm cov ntaub ntawv muag muag, thaum lub tiaj tiaj-tipped me ntsis yog qhov zoo dua rau cov khoom nyuaj. Lub kaum sab xis ntawm lub taub kuj tseem tuaj yeem sib txawv, nrog cov ces kaum sharper muab cov nrawm nrawm nrawm tab sis tsawg dua qhov tseeb.

Thib peb, cov shak ntawm lub laum me me yuav tsum tau ruaj khov thiab sib xws nrog lub cuab yeej drilling. Qee lub laum cov khoom muaj hexagonal shanks, uas muab lub zog tuav thiab tiv thaiv kev swb thaum lub sijhawm tho. Lwm tus muaj shanks, uas muaj ntau dua thiab ua haujlwm zoo rau feem ntau cov ntawv thov tshuab.

Thaum kawg, qhov loj ntawm laum me ntsis yog qhov tseem ceeb. Nws yuav tsum phim qhov loj me ntawm lub qhov yuav tsum tau ua rau txoj haujlwm. Laum cov khoom tuaj ntawm ntau qhov ntau thiab tsawg, los ntawm cov khoom me me rau cov hniav nyiaj hniav kub ua rau cov khoom loj rau kev tsim kho.

Ntxiv rau cov yam ntxwv tseem ceeb no, muaj lwm yam los txiav txim siab thaum xaiv lub laum me ntsis, xws li hom laum tau siv thiab cov khoom siv tau drilled. Qee cov ntawv laum laum tshwj xeeb tsim rau siv nrog qee yam ntaub ntawv, xws li masonry lossis hlau.

Zuag qhia tag nrho, cov laum zoo yuav tsum tau ua los ntawm cov ntaub ntawv ruaj ruaj, muaj cov lus qhia tsim tau zoo thiab shank, thiab yog qhov loj me rau kev siv cov ntawv thov drilling. Nrog cov yam ntxwv zoo li no hauv siab, cov kws tshaj lij thiab cov nyiam nyiam ib yam nkaus tuaj yeem xaiv lub laum txoj cai rau lawv cov haujlwm thiab ua tiav cov txiaj ntsig zoo tshaj plaws.
